1. Field of the Invention
The invention relates generally to beds and more specifically, to a bed configured to oscillate in three dimensions with or without seesawing motion.
2. Description of Related Art
A large portion of people complain that they have to lie down on a bed for a long time before they fall asleep; that they can not fall asleep again after they wake up during the night; or that they wake up early and can not fall asleep again in the early morning. In addition, many people suffer from insomnia or other sleep problems caused by physical or mental diseases. According to statistics, one fourth of the population suffers from insomnia; in adults over 76 years old, 29% of men and 37% of women have sleep problems. Drugs used for insomnia have certain limitations because of their side effects, which inhibit the action of the central nervous system for a certain period of time and can therefore affect a person's life quality. Moreover, there are considerations of drug-dependence that must be considered.
It is obvious that sleep is vitally important for human physical and mental health and therefore the sleep mechanism is an issue that is worth exploring and continuing to explore. Experiments involving lack of sleep suggest that sleep allows the body to rest and repair itself. Therefore, a new and effective hypnotherapy technology would be highly desirable.
The effect of some of the so-called hypnotherapies is questionable. One example is music hypnotherapy that relies on an aural stimulus, which only acts on the cochlear nerves and locally stimulates the certain cerebral cortex and the stimuli is excitative to the brain. Some special beds have been used in hospitals that have a special mattress and bed skeleton. However, the function of the bed is not mainly to treat insomnia but mainly to prevent patients who are unconscious or who have difficulty changing their posture from bedsores and pneumonia.
Traditional understanding of sleep in humans assumes that the quietness of the environment is an important factor. In conjunction with this assumption, it is the belief that a generally steady sleep surface is beneficial. However, this is an issue that merits further consideration. Actually a proper form and quantity of movement is an effective stimulation for promoting sleep and maintaining sleep based on the following existences. One example which I call cradle effect is a child being rocked in a cradle or rocked by a parent in the parent's arms. Another example which I call trip effect is when people fall asleep while traveling by a carriage, car, ship or train. The third example is that sleepiness caused by vehicle jolt is a major cause of serious traffic accidents proved by traffic accident surveys (Department of Human Science, Loughborough University Tel: +44-1509-223091) which belongs to the scope of the trip effect. In addition, generally, people change their posture a few times after they lie down and before they fall asleep.
Vestibular organs including the utricle, the saccule and the semicircular canals are traditionally understood as balance sense organs that are involved in evaluating the position of the head relative to gravity, liner acceleration or deceleration, and the movement of the head. Vestibular organs function to make human to sense posture, position and movement to maintain body balance. However, based on the above explanations, the vestibular organs are also sleep organs.
Based on study of sleep history, exquisite observation of human life and continuous exploration of sleep mechanism, applicant thinks that sleep mechanism consists of two contents that we may call sub-mechanisms: (1)the sleep initiation mechanism and (2)the sleep maintenance mechanism. Sleep occurrence is a process of a consciousness state entering a sleep (we call none or very low level consciousness) state and is triggered by the sleep initiation mechanism. Sleep occurrence depends on conditions both from outside and inside of the body. That is, both the environment and some organs of the body contribute the sleep initiation. As such, sleep occurrence is a conditioned reflex. Generally, the sleep maintenance mechanism is a natural, cerebral function program that is procedurally controlled by the brain although it is affected by conditions from inside and outside the body at a certain degree.
A factor affecting sleep initiation is motion sensed by the body. The proper motion is a motion that simultaneously satisfies two conditions: (1) quality: proper motion form that continuously stimulates vestibular organs—there are two motion forms: rhythmic and rhythm-less; (2) quantity: proper motion intensity that will not cause muscles, especially extremity muscles, to contract in an attempt to maintain body balance and will not cause excessive reaction of parasympathetic excitation. The proper motion gives appropriate stimuli to vestibular organs thereby promoting the occurrence of sleep.
Based on the foregoing information, I have established a theory about the mechanism of sleep occurrence. The content of the theory includes: sleep occurrence is a conditioned reflex relying on the vestibular organs; the vestibular organs are sleep sense organs that include the utricle, the saccule and the semicircular canals; and the brainstem and basal forebrain form the sleep center. Proper motion stimulates the vestibular organs; the hair cells of the vestibular organs are activated and create action potential which is a sleep signal; the sleep signal is transferred to a sleep center in the brainstem and the basal forebrain via the afferent neuron tract of vestibular nerve nucleus; the neurons of the sleep center are activated and sleep onset is triggered. Besides the above, vestibular nerve broadly connects with other structures, such as vagus nerve nucleus, which may provide more benefit for sleep and for human' health.
Therefore, it is desirable to provide a new method that moves in such a manner as to act on the sleep initiation mechanism and the sleep maintenance mechanism by proper stimulation of the vestibular organs and promote sleep initiation and help sleep maintenance
The vestibular organs play a role of sleep sense organs is the theoretic basis for the invention. The apparatus is different from a traditional bed in that: (1) its mattress and support plate (plate) below the mattress are movable. Once sleep starts or shortly after sleep starts, the mattress and the plate of the apparatus can be controlled to cease movement and acts as a normal bed or to vary the amplitude of movement to assist sleep maintenance; (2) the plate and the mattress is suspended in the air. As an apparatus for a hypnotherapy, the bed is different from other hypnotherapies in that it stimulates directly the sleep sense organs-vestibular organs and actively induces sleep occurrence which the effect is positive. Compared with other hypnotics, the invention has no side effect when the motion state is proper by maintained at certain intensity and form of the motion adjusts depending upon the person.
The plate which supports the mattress of the bed rhythmically moves forward and backward in three dimensions with or without seesawing motion, which provides an appropriate motion stimuli to the vestibular organs of inner ears. The stimulation to the vestibular nerves causes sleepiness and promotes sleep occurrence. The plate situated on an inner skeleton (skeleton). One end of at least four suspended cables (cables) connects to the outer inferior edge of two opposite sides of the skeleton and another end of cables connects to the inner superior edges of two opposite sides of a foundation. There are two motors sited on the bottom of the foundation of the bed that drive the skeleton to move. The motion created by bed is proper for a physical person. The “proper” motion contains three contents: 1) effective stimulation to the vestibular organs; 2) no reaction of balance adjustment which means the motion does not cause muscle contraction, especially extremity muscle contraction or body is in the posture that is unnecessary for muscle contraction to maintain balance; 3) no excessive reaction of the vagus nerves, such as nausea or/and vomiting. The user can choose the proper intensity and expectant motion fusion by a control panel fixed on the bed or a remote control device. The bed promotes sleep occurrence and maintains sleep. The bed also provides more comfort than a common bed. The bed is useful for all people, especially for people who have insomnia. It may benefit the patient who is unconsciousness or has difficulty changing his or her posture to prevent bedsores or pneumonia.
Tow exemplary embodiments are described as follow.
First exemplary embodiment: a mattress and a plate below the mattress are supported by a skeleton. One end of cables connects with the outer inferior edge of two long opposite sides of the skeleton and the other end of the cables connects with the inner superior edge of two opposite long sides of a foundation. The actual effect is that the mattress and plate situated on the top surface of the skeleton is suspended in the air. The cables run slantways from the inner inferior position at the inferior edge of the skeleton to the outer superior position at the superior edge of the foundation. So the two opposite sides of the mattress and the plate surface will be raised and lowered alternatively in the vertical direction at the transverse view when the bed moves fro and to in the transverse direction. The surface of the mattress and plate will move up and down alternatively in the vertical direction at the longitudinal view when the bed moves fro and to in the longitudinal direction. The first exemplary embodiment has the most complex motion form: three dimension motion+seesawing motion. Two motors provide motion power: one drives the mattress sited on the plate through the skeleton to move fro and to in the transverse direction and another motor drives the mattress sited on the plate through the skeleton to move fro and to in the longitudinal direction. Control panel or remote control device is for user to choose motion parameters.
Second exemplary embodiment: A mattress and a plate below the mattress are supported by a skeleton. One end of cables connects with the outer inferior edge of the skeleton and other end of the cables with inner superior edge of foundation. The cables run vertically from the inner inferior edge of two opposite long sides of skeleton to the outer superior edge of the two opposite long sides of foundation when the bed is at lowest potential status. The actual effect is that the mattress and plate situated on the skeleton are suspended in the air. The most complex motion form of this exemplary embodiment is three dimensions. Two motors provide motion power: one drives the mattress sited on the plate through the skeleton to move fro and to in the transverse direction and another drives the mattress sited on the plate through skeleton to move fro and to in the longitudinal direction. Control panel or remote control device is for the user to choose motion parameters.
We can design various motion forms by adjusting the rate of rotation of the two motors because the actual sense of user to the combination of the motions is a resultant motion.
Further advantages and scope of applicability of the present invention will become more clearly apparent from the consideration of the drawings and ensuing detailed description given hereinafter. It should be understood, however, that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from the detailed description.
The present invention will become better understood from the detailed description given herein below and the accompanying drawings that are given by way of illustration only, and do not limit the present invention and wherein:
A first exemplary embodiment of a bed 10 is shown in
Although the mattress 100, the plate 200, the skeleton 300, and the foundation 400 are shown as separate components, it is understood that one or more of these components can be combined into a single component. For example, the mattress 100 and the plate 200 could be provided as a single reinforced mattress.
For purposes of this invention, the mattress 100 can be any conventional mattress, such as, for example, a foam mattress, an air mattress, a spring mattress, a water-filled mattress, or any other mattress that is designed to support a body or bodies in a supine position and to provide a comfortable surface for a body or bodies. As shown in
Plate 200 is formed from any suitable planar material that is strong enough to support the weight of a body or bodies plus the weight of the mattress 100. The plate has an upper surface (not shown) that contacts the mattress 100 and a lower surface (not shown) that site on a skeleton 300(see

For a second exemplary embodiment, the drive mechanism also includes two motion devices that drive the skeleton to move fro and to in longitudinal direction and transverse direction separately and are showed separately on
As seen in
In operation either exemplary embodiment of the bed 10 or 20, a user may vary the motion form by choosing input parameters into a control module.
The parameters include frequency of oscillation of the mattress 100 including the liner when one motor works or oblique when two motors work or circular when two motors work simultaneously, the alteration of motion form and duration of oscillation of the mattress 100. User input device 610 may be either a control panel or a remote device configured to receive user inputs and transmit the inputs to control module 620. The control module 620, in turn, converts the user inputs into control signals to the appropriate electric motor(s) 430, 450.
While the above description contains my specifications, the reader should not consider these as limitations on the scope of the invention, but merely as exemplifications of certain embodiments thereof. The invention thus being described, it will be apparent that the same may be varied in many ways. For example, electric motor 430 and 450 can be replaced with a linear actuator or any other device that is configured to move plate in a transverse and longitudinal direction. We may alter the length of sticks 401, 402, 403 and 404 fixed on the foundation 400 (see
